One surprise constant on the Jaguars offensive line this season has been Guy Whimper, the tackle who has started in every game for the first time in his career. Before this season, Whimper had only ever made one start in his first five NFL seasons.

But the versatile tackle established himself on the Jaguars line.

"I wouldn't necessarily say I've been pleased because we're 1-5; I don't think anybody's really pleased," Whimper said. "I feel I'm very confident in what I do if I'm on the right side or left side. I think I put in enough work to go out there and compete with these guys."

Whimper has played both right and left tackle for the Jaguars, as injuries have dictated. The Jaguars picked up Whimper as a free agent last November after Britton tore his labrum in Kansas City.

So far, Whimper has been a significant upgrade. He learned a lot while going against the Giants' talented defensive linemen in practice.

"Going against Osi [Umeniyora] and [Justin] Tuck, even [Michael] Strahan, he taught me a lot my rookie year," Whimper said. "He'd tell me what I'm doing wrong, what technique I should be using vs. different moves that the defense does. That's very helpful."

Monroe practicing

Jaguars left tackle Eugene Monroe has been practicing fully this week, after a recurring shoulder stinger had sidelined him occasionally. Monroe suffered the injury during a one-on-one drill in practice before the Jaguars played the Carolina Panthers. He played with the injury in Carolina, then was held out of the Jaguars' game against the New Orleans Saints. Monroe returned against the Bengals, but didn't play at Pittsburgh last week.

"I banged it up a few times and just kept fighting through it and jacked it up pretty good in the second half," Monroe said.

Still, with full participation in practice all week, Monroe is getting closer to being able to play.

Britton, whose back tightened up Sunday morning in Pittsburgh, had an MRI earlier this week and said he received good news. Still, the lineman did not practice on Thursday or Friday.

Safety Courtney Greene did not practice either day.

Offensive lineman Jason Spitz (quadriceps) and safety Dawan Landry (thigh) were both listed as limited on the injury report.

Twelve other players were limited on Thursday but practiced fully on Friday.

"You put on the tape, and this guy is like a rolling ball of butcher knives," Pagano said. "He's scary. He runs over linebackers, he knocks guys out, he puts people to sleep. We've got to do a good job, as always, of setting the edge and not giving the outside. He's a downhill guy. He can bounce, jump, cut, spin. He can do everything, and we've got to get as many hats on as possible and hang on for dear life."

On the other side of the ball, Ravens' offensive coordinator Cam Cameron was asked Friday if Jaguars defensive tackle Tyson Alualu was a player that he expected to use double-teams on this week.

"Absolutely," Cameron said. "And, it would vary by play. You are always looking each game plan. The defense is trying to get single blocks, and we are trying to find ways to get double-teams. He would be one of those guys."

Still 2,000 tickets left

The Jaguars requested a 24-hour extension to sell enough tickets to avoid a blackout. As of Friday evening, they had 2,013 tickets left to sell.

They'll now have until 8:30 p.m. today to sell out all non-premium seats or make up the difference with comp tickets or a check to the NFL.

The Jaguars have not had a game blacked out since the 2009 season, when seven regular-season home games were blacked out.
